BOAT-LISTING APPARATUS.

Specification of Letters Patent.

Patented Sept. 28, 1920.

Application filed October 13, 1919, Serial No. 333,992. Renewed 5, 1920. Serial No. 401 562.

I '0 (all 10 how it may concern:

uWll that I, Anennr MCDOWELL, a he United States, residing at Los ngeies, in the county of Los Angeles and State of California, have invented certain new and useful Improvements in Boat-Listing Apparatus, of which the following is a specification.

This invention relates to means for listing boats whereby they may be cleaned and painted without the necessity of drydocking them.

Another object of the invention is to provide a barge with means for listing a boat to one side or another whereby the sides and keel may be exposed above the water surface for repairing, cleaning, painting, etc.

With the above and other objects in View, I have invented the device illustrated in the accompanying drawings, in which:

Figure l is an end elevation of a boat and barge showing the application of my invention, with the boat upright,

Fig. 2 is a similar view showing the boat listed,

Fig. 3 is a top plan view thereof,

Fig. 4 is an enlarged perspective View of the apparatus constituting the invention, and

Fig. 5 is an enlarged fragmentary view of a port hole and closure, and

Fig. 6 is a detail sectional view.

In the embodiment illustrated a boat 1 is shown of the tight deck class and 2 is a barge to be used as a support or base in connection with which the apparatus is to be used. Extending longitudinally of the barge is a base 3 having posts 4; and 5 which support booms 6 and 7 having forks 8 and 9 at one end and similar forks 10 and 11 at their other end. These forks are adapted to straddle booms 30 and 35 fixed to the masts 12 and 13 whereby the boat 1 and barge 2 are held the .desired distance apart and shifting of their relative positions prevented.

The booms 30 and 35 are mounted longitudinally on the barge 2 and boat 1 respectively. Boom 30 is supported in blocks 31 secured to the posts 1 and 5 on the sides thereof which oppose the boat 1. These blocks 31 are shown secured by clips 32. The boom 35 is similarly secured to the masts 12 and 13 by blocks 36 held by clips 37.

Blocks and tackles 1 1 and 15 are crossed from the outer ends of one boom to the inner end of the other to hold the boat and barge in parallel relation. Block andtackles 16 anu 17 are run from the posts 1 and 5 to the upper ends 18 and 19 of the masts 12 and 13 whereby the boat 1 may be listed by operating the tackles 16 and 17 until the side 20 and keel 21 of the boat 1 are exposed above the surface of the water, thus permitting repairing, cleaning, and painting of the boat without having to run it into drydock.

In listing the boat, the ballast 22 (shown dotted) in Figs. 1 and 2 is shifted to the side to which the boat is to be careened.

In Fig. 6 is a port hole closure 23 consisting of a plate 24, a gasket 25, a spider 26 and bolt 27 whereby the bolt holdsthe plate tightly against the gasket and pre vents water from entering the port hole.

When the boat is listed, the exposed side of the boat may be operated on from a raft 28 or small boat as desired.

Having now described my invention, that which I claim to be new and desire to procure by Letters Patent, is

1. In an apparatus of the class described,

the combination with a base and a boat to be listed; of means for holding the boat in spaced relation to said base, and cooperating means carried by said base and boat operable from the base whereby the boat may be tilted to any desired extent.

2. In an apparatus of the class described, the combination with a base and a boat to be listed; of booms carried by said base and boat, spacing booms arranged between said base and boat, and pivotally engaged and boat operable from .the base to list the boat.

4:. A boat listing apparatus comprising pivoted booms for connection with the masts of' the boat to be listed and with a fixed support, and means for cooperation with said booms to tilt the boat.

5. A boat listing apparatus comprising pivoted booms connected to the masts of the boat to be listed and to a support, posts to be carried by said support, and means connecting the boat and posts operable tolist the boat.

6-.- A boat listing apparatus embracing pivoted booms for connection tothe masts of the-boat and to a support, and a swivel connection between the masts and said support for tilting the boat.

7. A boat listing apparatus embracing pivoted booms for connection to the masts of a boat, posts to which said booms are Connected, and bracing guys for connecting said posts and masts.

8. A boat listing apparatus embracing pivoted booms for connection to the masts oithe boat and to posts on a support, said connection being a swivel connection, bracing means for connecting said posts and masts, and block and tackles for connecting said posts and the masts of the boat to be listed.

9. A boat listing apparatus embracing pivoted booms for connection to the masts of a boat, fixed posts located at a point spaced from the boat and to which said booms are connected, said connection being a swivel, bracing guys for connecting said posts and masts, block and tackles for connecting said posts and masts, a base upon which said posts are mounted, and ballast for assisting in the tilting of said boat. 7

10; An apparatus adapted for engagement with a boat to list it while in the water and holding it in listed position. a

1 1'. A boat listing apparatus comprising means for connection with a boat to be listed, and with a fixed support, and means for cooperation with said means to tilt the boat.

In testimony whereof I aflix my signature in presence of two witnesses.

ALBERT MCDOWELL.
